The hiking trail on the **vires du Pierroux** in the Dévoluy is a challenging and high-altitude route intended for experienced climbers. This trail offers sweeping views, exposed sections, and an intense sense of height. The starting point is the Hauts Gicons, and hikers are advised to wear a helmet for safety. The journey begins with an ascent to the summit of the Pierroux peak through the Queyras valley, a trail described as relatively straightforward, before moving to the west face, which leads directly to the summit. After reaching the summit, hikers follow the south ridge for a short distance before encountering a descent path that leads to a natural opening, signaling a transition to the east face of the mountain. The trail continues along a ridge that generally descends, crossing the entire east side toward the north. This path passes beneath the summit and leads down to the ridge of the Arche pass, covering roughly 1.5 kilometers. The route is noted for being extremely exposed above rocky outcrops and grassy slopes, where a slip could be dangerous. There are no fixed points to secure oneself along the way. At the end of the ridge, hikers must climb back toward another natural opening (a bit rough terrain) and then descend the other side, which is also delicate. Soon after, they turn left to begin a new ascent, crossing the Arche pass. Hikers are instructed not to continue down the trail toward Beaufin, as that would lead them back to the west side of the Pierroux. A clever and careful route—starting with a descent and then crossing to the left to reach a prominent large plateau—allows hikers to return above the Aiguillette through a final ascent, eventually rejoining the original trail used to climb the Pierroux. The area is described as having a breathtaking atmosphere and offering a high-flying, vertigo-inducing experience. This trail is not for the faint-hearted, but for those who seek a thrilling alpine adventure, it promises unforgettable views and a true test of skill and endurance.
